Ive got a slipper clutch on my 748 and its a bit of a pain in the arse. Its great on the motorway etc but town riding its quite grabby when im trying to go slow (30-ish). Im pretty sure mine could do with being stripped and cleaned but i was wondering if it would be worth fitting a stock one instead?

Anyone else using a slipper?

Cheers

Tom

cheers rene, yeah im not about to do anything drastic in a hurry, i was just wondering what other people think of slipper clutches and whether it'd be worth sourcing a stock one.

when you say adjust it, do you mean at the lever? if so thats not the problem, its just not designed to go slow lol

cheers for the link, good read.

at low revs/speed it feels as though it wants to pop out of gear and also makes some hissing and clicking noises. It kind of feels like im in too high a gear, even in first. The upshot is i have ride the clutch abit to maintain 20 or lower.

Ducati's are noisy beasts anyway - and the open clutch cover doesnt help lol. As i say, it defo needs a good clean which will hopefully sort it, or maybe some new plates at worst

Dry clutches tend to be a bit "grabby" apparently too, although I've only ridden with a dry clutch once and that was a stock 749 and around a racetrack so only rode on the clutch around the paddock and it didn't seem to bad to be honest, put a bit more snatchy compared to the wet clutch on my 600SS at the time

Ring a Ducati specialist like Luigimoto, JHP, Sigma etc up and ask them for their opinion

sounds like a plan. Ive also got Squirell7 (from this forum) on the case as he's literally just fitted a slipper clutch to one of his (many) ducatis, so he'll report back in due course.

cheers for all your comments

Ok so the 748 now has a slipper clutch


Went for a tootle round today and seems as problematic as yours does Tom. Jeez the clutch is a lot noisier now then it was before, sounds like using a pneumatic road hammer drill on a tin roof thats covered with nuts and bolts, especially with the open clutch cover. The gear change now seems quite a bit more clunky, to the point where you can hear the gear change. Riding below 3k revs is totally impossible, not bad when you are blasting round but a right pain in traffic. Not sure what gearing you have on Tom or what gearing I have on for that matter rofl but I have been riding the clutch all the time below about 20mph as well. That is the same or probs worse on the 916 and that doesn't have a slipper clutch. The 748 was prolly the same before but I think I have kinda got used to it and never really thought about it. Below 3k it kinda tries to buckaroo, like when you are learning to drive a car and let the clutch out too fast without enough revs. So I am sure that's just how they are mate, not the slipper clutch. I am relieved to feel that the clutch didn't get any heavier now it's fitted though. I doubt very much that I will anytime in the future have the riding ability to get the benefits, just fitted it as I thought it would be pretty trick


Any chance you can record and post a clip of the sounds that it is making as the hissing / clicking could be interpreted differently. Does it sound different when riding with the clutch out as opposed to just ticking over in neutral with the clutch out. I am really thinking that the noises that you are noticing are normal as well. When in neutral and ticking over and you pull the clutch in, the noise should be really dulled off by comparison. Similar to the difference between listening to music from a car stereo from outside the car with the door open and then with the door closed. Hope that makes sense, it's kinda similar in sound, just not as much rattle and dulled off


If you can post a sound clip that will help, I will have to see if I can make a sound clip for mine as well to compare.

Otherwise there are 2 main things to check, how worn are the plates and are any of the springs between the pressure plate and the friction plate broken. If the springs are broken then that might explain a few things. The plates have friction material on them that wear obviously but they also have teeth around the edge that wear so they wear in a rotational sense if you catch my drift, could also be the clutch basket as well that is worn where the teeth for the plates locate


I haven't read the link from above yet but thought that the adjustment of slipper clutches is to determine the amount of reverse torque that is eliminated and thus how much 'slip' it has
Will have a good read now though, could give room for thought.

thanks russ. ill see what i can do about a sound clip.

Its not the same noise that the duc makes when sat in neatral with clutch out (bag of spanners) or in (brooding drone), it only happens when in slow, geared-motion. To some degree i can illeviate it by riding the clutch to go slow, but it does occasionally slip and catch itself when doing so (without any further movement on the clutch lever from me).

Its reassuring that yours is similar!! - perhaps im mad to think i can commute on a duc!? i was going to have the clutch stripped, inspected and cleaned today, but the fella that was gunna help out is on an emergency job, so it'll have to wait until next weekend.


ill see what i can do about the clip, would definately help.
